When you create HTML page the width of an element is usually already specified (in percentage or in pixels), but the height can often vary, depending on the content.
Recently, I was repeatedly asked how to select a particular element in DOM, and this article will be entirely devoted to selectors in jQuery, perhaps most of them you have seen in various sources, but it's worth to put them together in one place.
There are a couple of cases where it is practical to use the tag base, for example, when the same images are in different structural parts of the site.

In CSS absolute and relative units are used to specify dimensions of various elements.
You can use styles to change the appearance of the cursor and select one of the fifteen available options.
With CSS, you can create bulleted and numbered lists, and also use an image as a substitute for list item.

CSS has several parameters to set the color of the text and background areas on a Web page.
